SUPPORT FOR CONDUCTORS F'iled Oct. 9, 1928 Inventor JJOMEB P UHANDLEB A ttof nay Patented Apr. 29, 1930 UNITED STATES PATENT rFi cE v HOMER P. CHANDLER, OF MANSFIELD, OHIO, ASSIGNOR TO THE OHIO BRASS COMPANY,

OF MANSFIELD, OHIO, A CORPORATION OF NE'W JERSEY surron'r non connncrons Application filed October 9, 1928.

My invention relates to supports for conductors and particularly conductors of the trolley wire class and in combination with means for guarding the trolley wire from contact with moving objects other than a current collector.

The object of my invention is to provide a simple, inexpensive device for supporting a trolley wire, particularly in mines, and pro vided with means for guarding the trolley wire from accidental contact with persons or.

animals in particular, and to provide a device in which the guards can be easily ap my invention shown in Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 2 and shows a holding lug or ear later described.

In the preferred embodiment of my inven- I tion I use a member 1 provided with a large flange 2 engaging the roof of a mine or other overhead support and also a threaded socket 3 adapted to engage a supporting stud 4 which is secured in a mine roof or overhead timber. The body member 1 is of an inverted cup-shaped member and has mounted therein and projecting therefrom a stud 5 having a lower threaded end 6 and an enlarged head 7. The stud 5 is mounted in the member 1 by means of insulating material 8 and which, together with insulating material 9, separates the member 5 electrically from the member 1. To the threaded end 6 is secured a clamp or car 10 to engage the trolley wire 11.

Projecting vertically or parallel with the axis A-A are spaced lugs or ears 12 which are shown diametrically opposite and positioned in parallel planes with each other. These lugs or cars are provided with a slot 13 Serial No. 311,357.

open at the top to receive a bolt or holding member 14. The lugs or cars 12 are provided with braces 15 which form a pocket to receive the head 1601 the bolt 14. The passage through the lug or ear 12, which I have termed a slot, may be circular or oblong and either closed or open at the top. For convenience I have used the term slot to describe these different forms. t is desirable to have the member 14 and the slot 13 so arranged that the member 14 can be attached or de tached as desired.

In order to secure the member 14 in position, a portion of the member 14 is threaded as indicated at 17 and a nut 18 is applied thereto which engages the lug 12 together with the head 16'. The braces 15 tend to prevent the head 16 from rotating. Slidably mounted upon the threaded portion of the bolt 14 are gripping members 19 and 20 provided with the hinge engagement 21 to per mit of adjustment of the lower projecting portions 22 and 23 and to maintain a definite separation of the upper ends of the members 19 and 20. The inner faces of the proj ections 22 and 23 are spaced apart to receive the guard board 24, preferably made of wood. In order to grip the board 24 in place between the inner faces 01": the members 19 and 20, I employ a nut 25 mounted upon the at some later time apply the guards 24 as. may be desired, or the guards may be removed at any time it is desired and very quickly and cheaply.

. I claim V I 1. A conductor support comprising an in verted cup-shaped member provided with means to secure it to an overhead support and means to secure the conductor to the said member in insulated relation thereto integrally and diametrically disposed means projecting upwardly from the inverted edge of the member and each provided with an open end slot, a headed and threaded member disposed in each slot and projecting therefrom and having a substantially common axis, ro-

tatable means on the threaded portion to se cure each headed member to its supporting means, a pair of separately formed holding members slidably and rotatably mounted on each headed member, means on each of the holding members to engage and rip an insulating member and hold the said means in fixed relation to the conductor, and means on the holding members to engage and permit the member to pivot about said engaging means and rotating means on each headed member to forcethe holding members together and into holding relation with the insulating member.

2. A conductor support comprising a body member having supporting means and means secured to and insulated from the body member to support the conductor, a pair of oppositely disposed ears integrally formed upon the body and projecting therefrom and each having a slot therein to receive a laterally projecting supporting member provided with a head and a threaded portion, the head to engage one side of supporting ear and a rotatable member on the threaded portion to engage the other side of the ear to secure the supporting members removably in place, spaced depending clamping means fromeach supporting member to engage and grip an insulating guard member and means on each supporting member to hold the clamping means in clamping relation with the guards.

3. A conductor support comprising an in-' sulated hanger having means to support it and means to support a conductor, spaced means pro]ectmg from the hanger and each having an open end slot and a detachable supporting member positioned in each slot, each supporting member provided with means to secure it to its said spaced means and provided with separably formed cla1nping members to receive a guard member therebetween and means to hold the clamping members upon the supporting members and in clamping relation to the guard members.

4. A conductor support comprising an insulated hanger having supporting means, means to support a conductor, spaced integral means projecting from the hanger and a slot in each spaced means to receive a supporting member; detachable supporting members positioned in the slots and in a common plane at right angles to the axis of the conductor support and having means to secure the members to the spaced means, means secured to each supportlng member to support a guard member and means to secure the said means to its guard member.

5. A conductor support comprising an inverted cup-shaped member having means to secure it to a support, a member to receive a support for a conductor, means to insulate the conductor supporting member from the cup-shaped member and means integrally formed with the cup-shaped member and positioned on opposite-sides of the said member and each having an opening therein adapted to receive a support member at right angles to the axis of the conductor support.

6. A conductor support comprising a grounded member, a supporting member to which a conductor is secured and means to insulate the support member from the grounded member, integrally formed and spaced means projecting from the grounded member and each having means to receive a laterally projecting support for a guard member. V

7 A conductor support comprising a grounded and an insulated portion, spaced means secured to the grounded portion and a guard support detachably secured to each spaced means, each guard support comprising a threaded and a headed bolt with a pair of nuts on the threaded portion to receive a spaced means between the head and one nut and spaced guard member supports between the said nuts, each pair oi guard member supports having means to grip a ard member therebetween.

In testimony whereof I aiiix my signature.
